This invention relates to a shelter structure commonly known as acabana, and more particularly to a collapsible cabana adapted to becompactly dismantled and packaged for transportation and storage andconveniently erected at a desired location.

Permanent cabanas are frequently employed at beach or swimming poolareas, to provide privacy for changing to and from bathing clothing, forstorage, for shade, and for siesta purposes, as well as for a myriad ofother uses. As a substitute for permanent cabana installations, resorthas lately been made to tents and similar structures which may bebrought in collapsed form to a convenient site, erected for a days use,and after use, dismantled.

Accordingly, it is an object of this invention to provide a portable,collapsible cabana assembly which may be easily and rapidly erected anddismantled, and featuring novel construction which permits the frameworkfor the cabana to serve, in the collapsed position, as a case forconveniently securing the component parts for facile transportation.

A further object of the invention is to provide a cabana structure ofthe type described, in which components of the structure form, in thecollapsed position of the said structure, a handle for convenientlycarrying the same.

Still a further object of this invention is to provide a collapsiblecabana structure susceptible of economical manufacture, which structure,in the erected position, is highly resistant to displacement under theinfluence of wind and the like.

To attain these objects and such further objects as may appear herein orbe hereinafter pointed out, I make reference to the accompanyingdrawings, forming a part thereof, in which- FIGURE 1 is a perspectiveview of a cabana in accordance with my invention, the cover member beingshown in dot and dash lines, to permit illustration of the framework;

I will now describe my invention wherein the cabana assembly consistsgenerally of a framework to which a cover member may conveniently befastened. The framework, which in the accompanying drawing isillustrated as being made of rigid members, tubular in cross-section,

center position (see FIGURE 6). v

sembly is collapsed, the struts 30 fold about their central PatentedJune 6, 1961 may be constructed of any of a wide variety of shapes andmaterials, tubular aluminum, as magnesium alloys, being preferred byreason of the combined advantages of lightness of weight and structuralrigidity.

The frame of my cabana comprises a pair of top frame members 10 ofgenerally U-shaped configuration, having a central base portion 11 andextending branches 12, the said branches having their ends 13 flattened,as is best shown in FIGURES 3 and 7.

The ends 13 of the branches 12 are pivotally mounted by bolting orriveting to spaced brackets 14, 14 which are upturned from the centralsupport member 15. The support 15 is additionally provided with parallelwalls or flanges 16 which serve to rigidify the latter, as well as toform with the said support 15 a downwardly directed channel.

The thus formed top frame is supported upon U-shaped legs members 17,17, comprising central bases 18 and depending legs 19.

The bases 11 of the top frames are pivotally mounted in parallelism tothe bases 18 of the leg member 17 by means of variable friction clamps20. The clamps 20 (see FIGURE 8) each comprise a pair of generally U-shaped nested brackets 21, 22, of a length to span the branches 11 and18 of the top and leg frames, respectively, and allow suflicientclearance to permit the interposition between the branches 11, 18, of abolt 23.

The upper ends 24, 25, of the brackets 21, 21, are bolted or otherwisefixedly secured to the top frame member 11, the lower ends 26, 27 of thesaid brackets forming sockets pivotally enclosing the bases 18 of theleg members 17.

It will be readily recognized that the freedom with which the bases 18of the leg members 17 may pivot relative to the base 11 of the top framemembers 10 may be controlled by tightening or loosening the adjustmentbolts 23.

The parallel top frame and leg bases 11 and 18 are provided at anintermediate point with recesses 28, 29, respectively, which recesseslie, in the erected position of the said cabana, normal to each other(see FIGURE 1), the said recesses 28, 29 being arranged to register (seeFIGURE 3) when the leg members 17 are pivoted relative to the top framemembers 10.

When the cabana structure is collapsed by pivoting the top frame members10 toward each other about the brackets 14, the paired recesses 28-28,29-29, will register, forming an opening entirely through the foldedstructure, which opening, providing finger clearance, is particularlyadapted to be used as a handle for carrying the latter.

The cabana structure, in its erected form, is rigidified by theinterposition between each leg 19 and the adjacent top frame branch 12,of a hinged strut 30. The strut 30 is pivotally connected to the framebranches 12 and legs 19 at the points 31 and 32, respectively. The upperleaf 33 of the strut 30 is provided with a stop lug 34, which lug isadapted to coact with a keeper recess 35 on the lower leaf 36, when thestrut 30 is manually forced to the past dead As the cabana aspivots 37(as is shown diagrammatically in an intermediate position in FIGURE 2),the folded struts in the completely collapsed position of said cabanaoccupying the space between the branches 12 and the legs 19 (see FIG-URE 3 The cabana assembly includes four leg extension members 38,arranged to be joined to the ends 39 of the leg members 19 to providegreater height. The said ends 39 are of smaller diameter than the bodyof the legs 19 and flare outwardly to define shoulders.

The extension members 38 are of a diameter snugly t0 telescope over theends 39 of the leg members 19, the shoulders 40 forming a stop for thesaid extension members.

Convenient storage space for the leg extension members 38 is provided bythe channel defined by the walls 16 and central support 15, wherein thefour said leg members 38 may be jammed and frictionally maintainedduring transportation of the collapsed device.

The erected cabana framework with inserted extension members is providedwith a Wind and sun shielding cloth cover member C, such as duck (seeFIGURE 1) adapted to be received by the said framework and affixedthereto by any of a number of known methods, such as by tyingbands oftape extending from corners and other portions of the said cover throughgrommet reinforced holes in the framework serving as anchors. The use ofzippers at various points on the cover to provide flaps or separableclosures is likewise suitably employed.

My cabana may be further increased in utility and modified by providingthe top frame members of plywood or a like rigid material, in which casethe said rigid top frame members would, with the walls 16 and centralsupport 15 form an enclosed carrying case for convenient transportationof the collapsed cabana.

The embodiment shown in FIGURE makes provision for a peaked gabledstorage space above the normal erected cabana. For purposes of thisembodiment, the top frame members 10 are provided on their upperperipheral edges with a series of spaced apertures 41. The corners ofthe said frame members are each pro vided with a transverse socket 42. Arigid, centrally foldable panel 43, of a size adapted to register withthe top frame 10, is provided on its undersurface with a series of snapfasteners 44 in position to mate with the apertures 41, when the panelis set atop the frames 10.

The peak structure 45 comprises a central ring 46 forming an apex, andfour extending strut members 47 having their free ends 48 arranged to beinserted within the corner sockets 42. The ends 48 of the struts 47 areprovided with shoulders 49 forming stops resting against the panel 43.

A peak cover 50, of general pyramidal outline, is provided optionallywith zippers or other fastening means 51 on one side, to permit accessto the storage space within the attic-like peak 45. The struts 47,outlining the pyramidal peak, may be slipped from their sockets andcollapsed for transportation.

By the above described structure, I have provided a. rigid cabana frameassembly susceptible of highly economical production occupying a minimalspace when dismantled to be conveniently transported to a rigidstructure, either extended to provide head room or with the extensionlegs removed for low wind resistance, or use as a picnic table if usedwith the removable panels in position.

The assembly, in the forms shown and described, features ease ofassembly and disassembly, coupled with the ability to be compactlystored for transportation, the frame members forming, in the collapsedposition of said cabana, a convenient carrying case for transportation.
